While the MP-16 pump is a sturdy piece of equipment, it is vulnerable to damage at
certain times, especially when inactive.
even the strongest materials, and cause subtle but significant damage to vital components
and systems. Unlike equipment that is in use, stored units generally do not receive regular
maintenance, and even small problems can become significant if not caught.
By storing the pump in accordance with the following guidelines, users may protect it from
environmental wear and tear.
2.2.1 General Storage Guidelines
If the MP-16 pump is to be idle for longer than a month, it should be prepared for storage.
Pumps should always be stored in a dry, temperature controlled environment to minimize
environmental effects and help to prevent equipment degradation. Pumps should never be
stored directly on the floor or ground, but elevated to avoid potential problems.
Fluid End
Remove the fluid end valves, pistons & liners. Clean the inside of the fluid end, including
all valves and parts, and coat all components in rust inhibiting oil. Then clean the liner wash
system and settling tank, and put clean oil into the liner wash system to prevent rusting.
Finally, coat the liner wash tank and inner spray parts with a rust inhibiting oil.
If the pump is expected to remain in storage for six (6) months or more, the fluid end
should be cleaned and flushed with water which has had its pH raised to 10 or more in order
to kill any sulfide reducing bacteria in the pump.
sufficient Hydrogen Sulfide to attack the hardened steel parts in the fluid end and harm or
even kill personnel when the pump is reopened.
Once the fluid end has been cleaned, 1 quart of internal rust inhibitor should be poured
into the suction and discharge ports of the fluid end, and pipe plugs should be installed in any
openings. Cover the entire pump with a plastic or canvas tarp to prevent exposure.
Power End
Remove the power end covers. Drain and clean the main sump and settling tank. Then
clean and coat all bearings and finished surfaces with rust inhibiting oil, rotating the driveshaft
during coating to ensure even coverage. Then coat all exposed metallic surfaces and the
entire inside surface of the power end with rust inhibiting oil, and replace all covers.
Raise the fluid end of the pump so the pump slopes downwards towards the power end
and secure in place. Replace the main sump drain with a 90° elbow pointed down, and cover
the opening with a wire mesh screen to permit air circulation and prevent condensation
buildup.
In addition, a 100 watt light bulb burning continuously will also help prevent
atmospheric water condensation.
A falling MP-16 pump can do significant damage to itself and has sufficient
mass to crush most anything in its path, causing catastrophic equipment
WARNING
failures, severe injury and death. When raising a pump, be sure that it is
firmly secured and supported, and all personnel should always give
suspended units a wide berth.
